Following changes made to **MatrixGenerics** in https://github.com/Bioconductor/MatrixGenerics/issues/23, need to update client packages such as **DelayedMatrixStats**. Process will be something like: - [ ] Add unit tests; something like https://github.com/HenrikBengtsson/matrixStats/blob/ff261339136ec7c5cb03a882449a50325f57c159/tests/rowCollapse.R#L16-L28 -...

# Background **matrixStats** uses `ties.method = "max"` as the default for `colRanks()` and `rowRanks()` for legacy reasons, but we want eventually update to `ties.method = "average"` to align it with...

Might be useful in the transition to the **MatrixGenerics** package. E.g., you'd only get the `matrix` method if **matrixStats** was installed. See https://ropensci.slack.com/archives/C026GCWKA/p1534959381000100 for a discussion on implementing conditional use...

Probably matching default value to whatever the implicit default is in **matrixStats**.

Like `rowAvgsPerColSet()`, but where `S` is list so that subsets can be of different lengths. Might restrict `FUN` to be support `cols` and `rows` arguments to promote efficient computation. See...

People might stick other matrix-like objects to construct a *DelayedMatrix*, e.g., *data.frame*, *DataFrame*, *tibble*, *data.table*. It will be hard/impossible to test all possibilities, but should perhaps test some of the...

Should use `BiocInstaller::biocLite()`
